25 If your brother becomes poor, and has to give up some of his land for money, his nearest relation may come and get back that which his brother has given up. 26 And if he has no one to get it back for him, and later he himself gets wealth and has enough money to get it back; 27 Then let him take into account the years from the time when he gave it up, and make up the loss for the rest of the years to him who took it, and so get back his property. 28 But if he is not able to get it back for himself, then it will be kept by him who gave a price for it, till the year of Jubilee; and in that year it will go back to its first owner and he will have his property again. 29 And if a man gives his house in a walled town for money, he has the right to get it back for the space of a full year after he has given it up. 30 And if he does not get it back by the end of the year, then the house in the town will become the property of him who gave the money for it, and of his children for ever; it will not go from him in the year of Jubilee.

Commentary on Leviticus 25:23-34
(Read Leviticus 25:23-34)
If the land were not redeemed before the year of jubilee, it then returned to him that sold or mortgaged it. This was a figure of the free grace of God in Christ; by which, and not by any price or merit of our own, we are restored to the favour of God. Houses in walled cities were more the fruits of their own industry than land in the country, which was the direct gift of God's bounty; therefore if a man sold a house in a city, he might redeem it only within a year after the sale. This encouraged strangers and proselytes to come and settle among them.
